Understanding as the plane of seeing (Buddhism)

This understanding belongs to the first of the four paths.

On the Path of Purification of Hinayana Buddhism, panna (understanding) is considered as of one kind (monad), of two kinds (dyads), of three kinds (triads) or of four kinds (tetrads). There are five dyads, four triads and two tetrads. All have the characteristic of penetrating the individual essences or true nature of states (monad). In the fifth dyad, this is contrasted with understanding being the plane of development or culture.
